A signed VPAT 2.5 your procurement counterparty will accept.
Two to three weeks. WCAG 2.2 AA, Revised Section 508, EN 301 549 where in scope. Signed under principal-engineer attestation. Designed for federal contractor procurement, healthcare RFP response, and EU public-sector tender.
$15,000–$28,000 Two to three weeks · T&M with cap
A schematic of a VPAT 2.5 INT cover page next to a stack of evidence dossiers — assistive-tech recordings, audit findings, SC-mapped citations — with a signature block in the foreground and a procurement counterparty label on the receiving end. Reads as "the artifact your procurement office actually accepts." Architectural, document-credentialed, no stock-handshake imagery.A self-attested checklist will not survive procurement counsel.
A federal contracting bid is due in three weeks. Or a healthcare RFP just asked for your VPAT 2.5 / ACR. Or an EU public-sector tender requires an EN 301 549 conformance statement against the property you are about to sell. The procurement counterparty wants a signed conformance artifact, not a self-attested checklist scored from a screenshot — and the deadline is real.
The market response is uneven. Some firms hand out VPAT templates with no underlying audit and a marketing-ops signature. Others deliver a stale VPAT 2.0 against WCAG 2.0, which is no longer procurement-current. Counsel reading the artifact under acquisition scrutiny will see the gaps; the bid response will land back in your inbox with the a11y rows flagged for remediation, and the deadline will already be past.
B1 is the engineering audit firm’s answer. We ground the VPAT in real audit evidence — your A1, a recent third-party audit, or a compact A1 we run in series — and produce a VPAT 2.5 INT against WCAG 2.2 AA, Revised Section 508, and (where in scope) EN 301 549. Every applicable row scored against the evidence. Every Partial / Not Supports row annotated with a remediation pointer. The artifact is signed by the BST principal who oversaw the audit, under principal-engineer attestation through Clarity House LLC. Procurement-defensible, counsel-defensible, deadline-credible.
What you get
-
Signed VPAT 2.5 INT
A VPAT 2.5 INT covering WCAG 2.2 AA, Revised Section 508, and (where in scope) EN 301 549 — the international edition procurement counterparties expect today. Every applicable success criterion scored Supports / Partially Supports / Does Not Support / Not Applicable, with remarks and explanations grounded in the underlying audit evidence.
-
Accessibility Conformance Report (ACR)
The narrative ACR companion to the VPAT — executive summary, scope statement, evaluation methodology, conformance scope, and revision history. The document procurement reads first; the VPAT is the table they verify against.
-
Underlying audit evidence dossier
The findings the VPAT is grounded in: WCAG 2.2 SC citations, page / template / element specificity, assistive-tech recordings (NVDA / JAWS / VoiceOver / TalkBack as scoped), and component file:line where the consumer ships on a known component library. Procurement-defensible under counsel review, not "trust the table."
-
Procurement-response packet
A buyer-side response template that maps your VPAT scoring to the most common federal contractor and healthcare RFP a11y question structures. Drop-in copy for the response document, calibrated to Section 508 acquisition language and HHS-flavored procurement.
-
Principal-engineer attestation
The VPAT 2.5 and ACR are signed by the BST principal who oversaw the audit, under principal-engineer attestation through Clarity House LLC. Note: this is principal-engineer attestation, not the regulatory third-party-assessor designation; we will tell you up front when your procurement context requires the latter.
-
60-minute procurement walkthrough
Walkthrough call with your sales-engineering counterpart, compliance lead, and (where present) counsel — every Supports / Partially Supports / Does Not Support row walked, with remediation pointers for any Partial / Not rows. Designed to land before you submit.
How it works
-
Kickoff & Evidence Intake
Day 0–2Deliverable Scope locked, audit evidence inventoried, jurisdiction overlays confirmed
Contract signed, scope locked, audit evidence inventoried. Where you bring an existing A1 audit (most common path), we read the findings and map them to the VPAT row structure. Where no underlying audit exists, we run a compact A1 first; the engagements then run in series. Jurisdiction overlays (Section 508 only, EN 301 549 added, AAA-bucket criterion claims) confirmed.
-
VPAT scoring
Days 3–8Deliverable Every applicable WCAG 2.2 SC scored with remarks and evidence pointers
Every applicable WCAG 2.2 SC, Section 508 functional performance criterion, and (where in scope) EN 301 549 clause scored against the audit evidence. Remarks written with the conformance reader in mind — clear, specific, defensible. Partial / Not Supports rows annotated with remediation pointer so the reader sees the path, not just the gap.
-
ACR narrative & QA
Days 9–12Deliverable ACR drafted, internal QA pass, procurement-response packet drafted
ACR narrative drafted — executive summary, scope, methodology, conformance statement, revision history. Internal QA pass against the underlying evidence to catch row / evidence drift. Procurement-response packet drafted in parallel.
-
Walkthrough & signature
Days 13–15Deliverable Walkthrough call, revisions incorporated, signed VPAT 2.5 + ACR delivered
Walkthrough call with your team. Revisions incorporated. VPAT 2.5 INT and ACR signed under principal-engineer attestation through Clarity House LLC. Procurement-response packet delivered alongside.
Pricing
Engagement model Time & materials with not-to-exceed cap
Standard tier (single property, WCAG 2.2 AA + Section 508 overlay, audit evidence supplied or produced from a recent A1) lands at $15K–$20K / 2 weeks. Cross-jurisdiction tier (WCAG 2.2 AA + Section 508 + EN 301 549 overlay) lands at $20K–$24K / 2–2.5 weeks. Complex tier (multi-locale property, AAA-bucket criterion claims included, or VPAT for a design-system-shipped consumer where the artifact rolls up multiple downstream surfaces) lands at $24K–$28K / 2.5–3 weeks. Time-and-materials with a not-to-exceed cap. Where bundled with A1, the two engagements run under a single unified cap with a small bundle discount.
Anchor pricing reflects typical engagement ranges. Actual fees are scoped per engagement under time-and-materials with a not-to-exceed cap. Pricing shown does not constitute a binding offer.

Often combined with
-
Single Property Accessibility Audit (A1)
A1 produces the audit evidence; B1 converts that evidence into the signed conformance artifact. Most-common mid-market entry combination — buyers often run them as a single engagement window with a unified cap.
-
Healthcare AI Compliance Review
When the procurement deadline driving the VPAT is a healthcare RFP, the BAA chain and HIPAA posture often need to land in the same window. WCAG audit + signed conformance artifact here, HIPAA / BAA / SaMD lens there.
